Populations of marine mammals, birds, fish and reptiles have declined by 49% since 1970, a report says.

The study says some species people rely on for food are faring even worse, noting a 74% drop in the populations of tuna and mackerel.

In addition to human activity such as overfishing, the report also says climate change is having an impact.

The document was prepared by the World Wildlife Fund and the Zoological Society of London.
